从if _ spec获得的版本号是一个32位的值，将之与0xffff进行AND计算可以得到主版本，右移16次可以得到次版本。

The version number retrieved from the if_spec is a 32 bit number which is ANDed with 0xffff to get the major version and right shifted 16 times to get the minor number.

利用传输门实现了32位桶式移位寄存器，其具体功能包括算术右移，逻辑左移，逻辑右移和循环右移。

In this paper, we realized Barrel Shifter of 32 bits by using transpost gates, its functions including arithmetic shift right, logic shift left, logic shift right and rotate right.
